Parameter Estimates

Model Insight

Estimated persistence of 1.000 is at or above 1 (non-stationary): volatility shocks do not decay and the long-run variance is undefined, so long-horizon forecasts should be treated with caution.

Inverse leverage: Positive returns increase volatility 48% more than negative returns
